I have. Completely safe and competant. First time we met at Cannon lot, Jacques wanted to lead Duet Direct, and would not take a word of beta. He did one of the best dig deep not to hang leads I have ever seen in 35 years, got it onsight, no hangs. Then we did Union Jack and Reppy's.
Next time I led Turner's Flake, and Jacques led Lancelot Link, and I led Pine Tree. We had a snack and walked to Whitehorse and did Sliding Board, then walked back.
Time after that was Sugarloaf I think.
Despite what one of his detractors recently posted, that he is some trad gumby, he's actually quite solid. I'm a trad gumby. I place gear on sport climbs.
You might be surprised how many very skilled climbers have climbed with him.
The car is another story....lol.
